Vehicle Restraint Modules With Precast Foundations for Rapid Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing vehicle restraint and noise protection modules on roadways cause significant roadway restrictions and traffic obstructions due to the need for on-site concrete pouring and anchoring, which prolong construction times and pose safety risks.
Innovation Solution
The use of prefabricated vehicle restraint and noise protection modules, comprising a precast concrete strip as a base module, which are installed in pre-dug foundation pits, allowing for faster assembly and stable anchoring without the need for on-site concrete curing, and can be connected using guide rails and anchors for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If on-site concrete pouring and anchoring is used for installing restraint modules, then stable anchoring is achieved, but construction time is prolonged and roadway restrictions are significant
Solution Approach 1:
The concrete base is pre-cast and pre-cured in a controlled factory environment before delivery to the construction site. This preliminary action eliminates the need for on-site concrete pouring and curing, reducing construction time from weeks to days while maintaining anchoring stability through pre-installed anchor points and reinforced结构设计.
Solution Approach 2:
The restraint system is divided into modular components: pre-cast concrete base modules with integrated anchor points, and separate restraint rail sections. This segmentation allows for rapid assembly by simply connecting pre-fabricated components together, eliminating time-consuming on-site concrete work while ensuring stable anchoring through factory-prepared connection points.
2Reliability
If on-site concrete pouring is used, then anchoring stability is achieved, but traffic obstructions and roadway restrictions are caused
Solution Approach 1:
The concrete bases are pre-cast and cured in advance at a factory, so that when they arrive at the construction site, they require minimal installation time. This preliminary preparation eliminates the need for prolonged on-site concrete curing, maintaining anchoring stability while minimizing traffic obstructions and preserving roadway capacity during installation.
Solution Approach 2:
The system uses modular pre-cast base sections that can be independently installed in short segments along the roadway. This segmentation allows construction to proceed in small sections without closing entire roadways, maintaining anchoring stability through each module while preserving overall roadway capacity for traffic flow.
3Productivity
If individual posts are driven into the ground, then installation speed is improved, but anchoring stability and continuity are reduced
Solution Approach 1:
The invention merges the advantages of both approaches by using pre-cast concrete base modules that combine the installation speed of driven posts with the anchoring stability of concrete foundations. The pre-cast bases are rapidly installed like individual posts but provide continuous, stable anchoring through their reinforced concrete construction and integrated anchor points, eliminating the need for separate concrete pouring steps.
